Guys, I have a problem with the proximity sensor on my Captivate.
The issue is that while on a call, when holding the device between my ear and my shoulder, the proximity sensor causes the screen to turn on, and starts randomly hitting buttons. So I tested it.
The proximity sensor works perfectly when the phone is "standing" on end and the proximity sensor is covered. It does NOT work (the screen does not turn off) when the phone is laying flat and you cover the sensor.
So bottom line, when the phone is standing 90 degrees, the proximity sensor turns the screen off when there's no light. When the phone is 180 degrees (or anywhere near it), even when there is no light, the sensor does not turn the phone off.
Is there any way for me to tweak the sensor at all using an app? Or is my phone defective?
Thanks.
With the phone flat on the table and I make a call, using my finger to cover the sensor the screen goes off. I try to twist and turn the phone in all angles and the screen is still off. Not sure if it's related but I had the same problems with the screen coming on when using my shoulder and cheek to hold phone.
My hair was a little longer and I think the hairs blocked the sensors.

I just did the same thing. With the phone flat on the table and I make a call, cover the proximity sensor with my finger, the screen stays ON. The minute I put the phone up 90 degrees, the screen shuts off.
What's going on?

Perhaps you are running a different combination of kernel/rom? One that takes into account the devices orientation when engaging the proximity sensor?
I've never actually tested this, but I know I had various degrees of proximity sensor problems running certain ROMs. So maybe try a different combination?

Doesn't actually sorry...
Haven't used any of the Cognition ROMs in quite a while. DesignGears has a nice IRC channel though where lots of people tend to hang out. Maybe hop over there and politely ask around to see if anyone else has had the same problem? Asking within a group of Cognition users might get you more help than the XDA population in general.
All I can say is that with my i9000 kernel/radio/rom combo, my proximity sensor is not affected by the device orientation. Also, you could try running a proximity sensor test and see what happens, just to rule out defective hardware.
*#*#0588#*#* – Proximity sensor test
Hope that helps.

I can confirm using the proximity sensor test that it works fine. Proximity sensor only has two states, 1 and 0, correct? No matter the way I hold the phone, the proximity sensor test shows it running perfectly.
Does this mean that there's a problem with the ROM? Is it possible for me to simply replace the phone.apk?
Edit: Here's the EXACT problem I'm having. http://code.google.com/p/cyanogenmod/issues/detail?id=1916
I have this same issue!! I HATE IT! I have considered going BACK to my iphone because of it! I get tired of muting people and ending calls
ETA: I am using the leaked 2.2 Froyo not cognition
Does anyone know how to fix this? It's getting REALLY annoying!!
Does anyone know if dg is going to fix this in Perception?

Does it work if you flash back to the stock ROM? If it works on stock then it's a problem with the ROM, If it doesn't work on stock then it could be a problem with your phone...

Yes. Flashing back to stock ROM it works perfectly. Any of the Froyo ROMs, it does not work. Cyanogenmod fixed this in his ROMs, but I am not sure if dg plans to implement this in his ROMs. :-( Unfortunately, this behavior is by design in Froyo. Google decided that during a call, it makes more sense that as soon as your phone is put in a horizontal position, that the accelerometer overrides the proximity sensor and disables it. Their decision makes no sense, because it then invalidates the need for a prox sensor in the first place.

i think its cognition. i didnt test it but i had the problem during calls, i figured it was sesitivity not position but like i said i never tested it . i think its a jj4 bug. now im using perception and it works better.

It's not Cognition. It's Froyo. Google made the choice to have the accelerometer disable the prox sensor as soon as the phone was oriented horizontally. I can't see in what situation that would make any sense at all.
Still no answer for fixing this? I am not using cognition, I am using the leaked Froyo...
FYI, im in stock eclair. I have this issue.

I'm running cognition b7 and have the same issue but just hit the power button to manually toggle the screen in a horizontal position during a call. Hardly an inconvenience.

Eclair does not have the problem at all. Tried, tested and true. If you have the problem with stock Eclair, something is physically wrong with your phone.

That's not the point. The point is that they gimped Froyo on purpose, and for what, I don't know. It's counter-intuitive.
Just so you know, my co-worker has the Nexus S, which is basically the exact same phone as ours, except with Gingerbread. Guess what? It's FIXED on Gingerbread. Figures.
After use for a period of time my screen will start to create these dead spots and it prevents the phone from detecting my finger in that specific area how can i fix this without restarting my phone everytime this occurs?
I have this issue also, however it is very uncommon for me and simply locking the screen and unlocking it has resolved the issue.

Natic, your problem is common and known since gingerbread i believe. Wulamoc is correct, the easiest fix is just cycle your screen on/off with the power button as described.
hello,
i've also been having issues with "dead spots" on my Inspire's touch screen. it's about 1 centimeter wide and runs down the entire left side of the touchscreen. it pretty much renders typing in portrait mode useless because my E, S, & Z keys cannot be pressed because they are in the dead zone. luckily i can still type in landscape so it isn't too bad.
what is really weird is when i use the phone normally and i swipe over the dead spot the screen jumps because it's not registering over that small area. BUT when i swipe my finger across the dead zone REALLY fast back and forth, the touches register! i've tested this using an app from the Play Store called "Touch Test".
Just so you know i have rooted my phone and flashed a few ROMs already, i've seen in other posts that this sometimes happens on certain ROMs but the dead spots are usually alleviated with a reboot, turning the screen off, turning the device into landscape mode or as a last resort wiping the device. I've tried all of those and to no avail. i've used CM7 and aospX, but the problem started when i was on CM7.
i'm hoping that this is just something to do with software and i may be able to fix it myself without taking the phone apart and replacing anything. i don't have the dexterity for that i am already out of warranty and none of the current phones on AT&T interest me at the moment so i wanted to make this phone last as long as i could..
any type of advice on how i could fix this would be appreciated..
thanks in advance

I'd say that the part where you're in luck is that a lot of people are always after the new thing. You should start seeing Inspires on eBay and Craigslist at an awesome discount. Good luck to you, I'm in the same boat, I honestly can't see moving away from the Inspire until AT LEAST upgrade time.

You won't find a better at&t phone for what the inspire goes for. Replacing the screen could be cheaper but then again you might destroy it. You could sell it on eBay as a fixer and put what you get toward a working replacement.

Replacing it myself isn't an option for me. I am almost certain that doing that will end up with disaster. I was hoping it was a software fix, where wiping the phone or factory resetting would work.. But if all else fails I could tough it out and wait for the AT&T One XL..

I've noticed a few times when my phone vibrates and its pretty much flat the screen sometimes rotates. Not sure if this is a normal thing happening with most phones, I'm assuming the vibrate motor is confusing the accelerometer somewhat.
You can see a video of it happening below. The phone is flat against the table. Vibrate is set at 63 which I believe is close to stock. It happens on 50 too.
youtube: http://www.youtube.com/watch?v=-iuo7zsbCj8&feature=youtu.be
Could someone else try this? The app is free. Just switch to auto and set it to something like 0.999 and repeat. Obviously make sure auto rotate is enabled

I've always found the auto rotate on android a bit over sensitive, just trying to figure out if this might be a fault with mine.
Its done it to me before when my phone was laying on my bed charging

Yes, I used the test your android app and vibrate on short bursts. I think camera lens is tilting the phone. It was on a flat desk.
Ahh sorry was trying to quote the other guy on my phone but screwed up. Thanks for letting me know. my phones in a case and it does the same.

Yeah when it vibrated while laying flat the screen would auto rotate in no particular direction.

Old thread, but it happens to me when I'm playing some games. Vibrates and the screen flicks upside down, then back to proper orientation. I'm holding it in my hands and it's not totally flat either, so it's really getting thrown out of whack for a moment, then re-orients. Doesn't happen in every game, doesn't happen for every vibration, but it happens enough to be annoying.

Anyone knows a fix for this? It seems to be a hardware issue. Did you guys send to technical repair?
Hello everyone!
I have been visiting the site for a long time but this is the first time I actually post.
Well the problem I have with my nexus is that the screen stopped working a few days ago, but the touchscreen is still responding. I was walking at the beach with the phone in my pocket and after some time I realized the phone was not working. I suppose it was the humidity because the phone was completely dry.
Now the weird thing is that the touchscreen works perfectly, I can feel it when I unblock the phone, but the screen is completely black. Anyone has any idea how to fix this? I already changed the screen of my old nexus 4 a few times, but is there any other option? because I do not want to pay for the whole screen replacement when the touchscreen is working. I would say that it is just some contacts not working properly, but I do not really know how to fix that.
I hope someone has an idea how to fix it.
Thank you!
Maybe this thread will point in the right direction. Mentioned is flashing stock recovery.

Thanks for the reply! I tried that but it did not work and after the battery run out I realized it was not charging either. So I think the only thing left is to send it to repair to LG or something...
I went to use Waze for the first time on the S6 today, and it was all messed up. Unsure of what the problem was, I googled for compass calibration, and it was completely uncalibrated.
Calibration was easy, though, I just need to wait until tomorrow to check if it has solved the Waze problem.

Thanks for this! This fixed my Google Maps issue. The Maps pointer direction for my location did not point in the correct direction.
Hi and thanks for the advice.

Thanks for the heads up. I'll keep an eye out for it then.
I'm experiencing the same issue. It seems calibration helps only for some time as the problem returns. Looks really strange. I verified it on two S6 units.

That's unfortunate. I'm still calibrated since I started this thread, still keeping my eye out for it to lose calibration. Maybe I got lucky.
I noticed that after calibration compass works great, but after I restart the device the compass needs a recalibration. I did some quick search on XDA and it seems it is quite common issue across different Samsung devices, the question if it is a hardware or software fault.

I haven't rebooted my phone very often... rebooting now to see if it messes it up...
!!!!!!!!!!!!!!!!! Wow. Yep. That did it. Red needle w/ "0". Not cool, Samsung. Thanks for the heads up on this.
I visited Samsung Brand Store today and checked another 2 devices. Guess what ?! The same issue ! Compass calibration lost after reboot. This makes me think it is a software issue as it is hard to believe all 4 devices I checked were faulty. I also noticed it is very easy to calibrate it. You don't have to do all the calibration moves, you don't have to run any compass application or go into Samsung service menu (*#0*#0). You just have to be at your home screen or any other application and then you have to do the 3rd calibration move showed here: https://support.google.com/gmm/answer/6145351?hl=en
You just need to do it slower than showed on the image and with more angle. 3 moves and compass is calibrated.
I think most people didn't even notice this issue because:
- you don't reboot your device too often
- if you shake the device accidentally it might calibrate automatically
- most people do not use compass sensor too often (I personally use it once, twice per year and normally I would not notice it if not testing the device thoroughly as part of the 'new purchase checks').
So for me it is not a big deal to do 3 moves on occassion, but hopefully Samsung will solve it with OTA.

This isn't Samsung specific: every Android device I've ever had loses compass calibration upon reboot.

It would bother me less if there was a notification that popped up and said "Compass out of calibration, please calibrate", and then showed an animation like in misiek's link. (since the vast majority of users have no idea there is a compass in there, let alone that it needs calibration for some of their favorite apps to work.) That said, it shouldn't lose calibration.
I have a question to all of you having compass calibration issue. Do you happen to use a magnetic case (like magnetic closure/flap, magnetic catch holding, magnetic clips etc.) ?
